HOT-AIR HEATING SYSTEM.

Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed June 7, 1911. Serial No. 631,731

To all whom it may concern Be it known that I, JOHN E. citizen of the United States, residing at Flint. in the county of Genesce and State of Michigan, have invented certain new and useful Improvements in Hot-Air Heating Systems, of which the following is a specification.

This invention relates to improvements in hot-air heating systems and has for its principal object to provide a cheap system of this character which will obviate the necessity for the usual amount of piping.

Another object is to provide a hot air heating system which will effectively heat a. plurality of rooms on each of several stories of a house with the use of a minimum amount of hot air conducting pipes.

These and other objects will be apparent from the following description and with particular reference to the accompanying drawings, it being understood that changes in the specific structure shown and described may bemade within the scope of the claims without departing from the spirit of the invention.

In the drawings: Figure 1 is a veiFical section through two floors in a dw ling showing the method of heating two stories, the furnace being partly broken away, Fig. 2 is a plan view of the floor of the second story showing the gratings, the wall being SELTZER, a

in section, Fig. 3 is an enlarged section on the line 3-3 of Fig. 1.

Referring particularly to the accompanying drawings, and especially to Fig. 1 there is shown a furnace structure represented as a whole by the reference character 10. This furnace structure includes the outer inclosing wall 11, the inner concentrically arranged wall 12 which provides an intermediate cold air return chamber 13 and the inner hot air chamber 14, and the fire box 12 disposed at the bottom of the space within the wall 12. Mounted on the top of the wall 12, and extending into the wall 25 between the rooms A and B .of the first floor. is a drum 22, the upper portion of which has the inclined latticed sides 26 disposed in the rooms A and B, thelower end of the drum being open and communicating directly with the hot air chamber 14. Mounted on the floor in feach of the rooms A and B, and at the iplg'rer ends of the latticed portions 26 are gratings" 21 these gratings being disposed over the space between the upper ends of the walls 11 and 12 and arranged to peri drum 22. A'piv'oted depending door 20 is of each of the latticed sides 26, and eac of these doors carries a. notched operating stem 15 which extends through the latticed wall for adjusting the said door into open or closed position. By closing either of these doors, heat will be prevented frg n passing out of the grating to the adjacent room. The upper end of the drum 22 is formed with a nipple 27 to which is connected the lower end of a hot air conducting pipe 28 which extends vertically through the wall 25, and terminates below the floor of the rooms A and B of the second floor. Seated in the floors of these rooms A and B are the gratings 21', and disposed under these gratings and connected to the upper end of the pipe 28 is a funnel-shaped member 29 which is arranged .to discharge hot air through both of the gratings 21'. These gratings 21" are disposed close to the dividing wall 25' as shown. Extending through the wall 11 is a fresh air conducting pipe 24. the outer end of which communicates with the air outside of the building while the inner end is secured withinone of the openings 23 to conduct fresh air into the space around the fire pot. this air being then heated and passing up through the hot air chamber 14 into rooms A. and B and A and B! From the foregoing it will readily be seen that I have provided a simple, cheap and effective hot air heating system wherein a room or rooms may be easily heatedwithout the necessity of the extensive piping systems in common use with the hot-air furnaces, and in which gratings conduct the heated air into the rooin or rooms, and conduct the cold air therefrom.

- What is claimed is:

1. A hot air heating system including a furnace, an inner casing spaced therefrom and forming therewith a hot air chamber. an outer casing forming with the inner casing a cold air chamber, a vertically extending hot air drum mounted on the'top of the indispos'ed inwardl ner casing and having apereured sides, e hot air flue extending fl'ein the drum to the floors of rooms of the upper story, a funnel mounted on the upper end 05 the fine,
